Time difference between Honolulu and Warsaw

Warsaw is 12 hours ahead of Honolulu

Honolulu, the United States is UTC−10 · Warsaw, Poland is UTC+1 — on standard time

The gap is not the same all year

Every converter gives one number for this pair. That number is right for most of the year and wrong for part of it, because Honolulu does not change its clocks and Warsaw goes forward on the last Sunday in March and back on the last Sunday in October.

Honolulu stays put all year while Warsaw moves, so the gap changes twice a year from Warsaw's side alone. A recurring meeting set in Honolulu's calendar will drift by an hour without anyone touching it.

When they can both be at their desks

Nine-to-five in Honolulu and nine-to-five in Warsaw do not overlap at all. With 12 hours between them, one side is always outside working hours, and the practical question is which side takes the early start or the late finish rather than when to meet.
